It ;; accomodates the needs of applications making use of glib or gtk+ (with "or" ;; to be interpreted in the mathematical sense). This is achieved by adding ;; two phases run after the 'install' phase: ;; ;; 'glib-or-gtk-wrap' phase: ;; ;; a) This phase looks for GSettings schemas, GIO modules and theming data. ;; If any of these is found in any input package, then all programs in ;; "out/bin" are wrapped in scripts defining the nedessary environment ;; variables. ;; ;; b) Looks for the existence of "libdir/gtk-3.0" directories in all input ;; packages. If any is found, then the environment variable "GTK_PATH" is ;; suitably set and added to the wrappers. The variable "GTK_PATH" has been ;; preferred over "GTK_EXE_PREFIX" because the latter can only point to a ;; single directory, while we may need to point to several ones. ;; ;; 'glib-or-gtk-compile-schemas' phase: ;; ;; Looks for the presence of "out/share/glib-2.0/schemas". If that directory ;; exists and does not include a file named "gschemas.compiled", then ;; "glib-compile-schemas" is run in that directory. ;; ;; Code: (define %default-modules ;; Build-side modules made available in the build environment.
